Based on the graph, the slope of the line is -1/2 because the slope is negative, as it is going down 1 unit and then 2 units to the left.
The y-intercept(b), where x = 0, is -1
So your equation is:
y ? -1/2x - 1
The shaded area is above the line, which means that y is greater than "-1/2x - 1"
The inequality is:
y ≥ -1/2x - 1
The answer is A
